IMPROVEMENT IN sAWrNe-MACHINE. v Y

The Schedule referred tc in these Letters Patent and. making part of the same.

hereby declare that' the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making apart of this specification, 1n `which is showna perspective vie'wof 'my improved device.`

My invention has for its object the production of a combined machine, capable of performing the hereto-V `fore separate operations. of felling, vcross-cutting, and `ripping trees; andt this end,

It consists ini the" peculiar construction and arrangevment of the several parts, by `means of which, when combined, a device is produced whiclnwhile capable -of performing allof the before-mentioned offices, Ashall `'cost but little more than though adapted to perform butone ofthem. A I v i' In the annexed drawing- A and A represent four pieces of timber, placed horizontally and parallel with each other, and secured together by means ot' thecross-stri`ps A' and A', near the centre and at the ends of said pieces. Extending downward, and to the front or rear, areV i `four 'supporting-braces, B,`having their upper ends `mortised within fthe centre` strips A, and their lower ends similarly secured within twopieces of timber, C- and C, the who'le 'forming the frame or support for the working-parts of the machine. i

D represents a shaft, provided with a crank, d,.at its centre, and `suitably journalled within boxe'sll and E, secured upon horizontal strips F F, extending across om onebrace B` tothe other.

Aiy-wheel,G,`is secured upon said shaft, ncarthe crank, and a pinion,.H,`iskeyed upon either endlthereof, outsideof the journals, which pinions mesh with and receive motion from twogear-wheels, I and I, secured upon a shaft, K, 'journalled in suitable boxes, k and k, upon the upper partof the frame;

A pitman, L, is ]ournalled at one end upon the vcrank d, and pivoted at the other end to across-cut saw, M, which, whcnthe shaft D is caused to revolve, `is given the usual longitudinal reciprocating motion.`

- "The pit-man L is pivoted, near its outer end, within the lower end of a supporting-strip, N, having secured i to its upper end across-bar, n, which is, in turn, pivoted at its cndswithin the uprights O and4 O. By this arrangement, the pitman is kept in position ver-1 tically, while allowed to mdve longitudinally with per- Four iron bars, o orare pivoted at their ,inner ends from one ofthe uprights4 O, i's a forked bar, l), having pivoted within Jits outer end a lever, 1t, which'is,in turn, pivoted at its outer end to one end ofthe crosscut saw S, and at'its inner end to the pitman T.

Thefpitman T, being journalledfupon a crank-pin,

h, secured Within the face of the Ipinion H, it will be readily seen'that when the shaft D is caused to re volve, a reciprocating motion will be communicated to the saw S.

The face of the saw being in'a horizontal position,

it is only necessary that it shall be properly supported, and caused to press against a standing tree, when in operation, to enable it to quickly and easily fell Or'cut down said tree'.

- To accomplish this object, a guide, U, provided with Aa vertical and a horizontal longitudinal slot, is secured at one end to a post, V, driven into the ground, near thet-ree, and furnishes la support for the saw, which passes through the before-mentioned horizontal slot n. j A block, W, is placed upon the guide, and is provided with a tongue, which, corresponding in width with the vertical slot u', passes downward through the same, immediately in rear of the saw.

A cord, x, is attached to said block, and, passing over the end `of the guide, has secured toits outer end a weight, X, which is suiiiciently heavy to cause said `block to press against the back of the saw withsulli-V cient force to give said saw thenecessary out, which pressure upon/said saw isv maintained as it ads-'ances through the tree. a

The inner frame-timbersrA extend forward of the -frame, as shown, and furnish a support for a shaft,.A,

which is suitably jonrhalled thereon. p

A circular saw, B', is placed near one end of said shaft, and a pulley, C", near the other end, which pulley, being connected with the y-ivhcel G, by means of a belt, c, receives andcommunicates motion Afrom said wheel to,said shaft and saw, and enables the slitting of trees, which have been felled and cut, into suitable lengths, by th hereinbefOre-described devices.

It will be seen that by this construction and arrangement of parts, a compact and convenient portable ma` chine is produced, capable of felling, cutting. up, and slitting into boards, trees of ordinary size, by which means great' economy is secured-in time, and the cost of the lumber correspondingly reduced.

Having thus fully set forth the nature and merits of my improvement,

What -I claim as new, anddesire to secure by Letters Patent, is-

The hereinbefore-deseribed device, when constructed and operated substantially as and for the purpose specified.
